We're dividing 649670 by 15 
The aim is to understand the frequency of 15 in 649670.

Moving on to step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 15

Going ahead to step 2:
When dividing 64 by 15, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 60 from 64, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 15

Going ahead to step 3:
49 divided by 15 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 45 away from 49, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 15

Step 4:
15 goes into 46 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 433.0
Subtract 45 from 46 to get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 15

Let's proceed to step 5:
If we divide 17 by 15, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 4331.0
Subtract 15 from 17 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 15

Going ahead to step 6:
20 divided by 15 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 43311.0
If we take 15 away from 20, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 43311.3
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 43311.33
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 43311.33, with a leftover of 0.005.
